Results of tests performed in accordance with 4. Acceptance criteria for these bolt stresses shall be based on recognized codes and standards.

An example of a bearing stress is the contact stress between the dogs and the loading shoulder of a dog coupling. A bending stress is a stress induced by a bending moment. A minimum of two Brinell hardness tests shall be performed on the QTC after the? A mechanical means for connecting two joints of riser pipe end-to-end. A pure shear stress in a section is the average stress induced by a force transverse to the section.

Neither should anything contained in the publication be construed as insuring anyone against liability for infringement of letters patent. The following are the allowable stresses that must be satis? IFP has then proposed a simple approach that applies to non-axisymmetric geometries of connectors. These tests and those described in 4. Using this relationship, the calculated riser pipe stress at the middle of the pipe wall caused by pure bending is treated the same as that caused by pure tension.


The make-up length, butt weld to butt weld, shall be documented. G16R01 Not for Resale. This publication will no longer be in effect? The determination of a riser’s response to the environmental loading and determination of the mechanical loads acting upon and developed within the riser require specialized computer modeling and analysis. Shibboleth is an access management service specc provides single sign-on protected resources.

API Product Specification

The coupling design load shall be applied to verify any assumption made in the analysis regarding separation. Next, the membrane and bending stress components must be categorized into one of the following stress categories: The formulation and publication of API standards is not intended in any way to inhibit anyone from using any other practices.

This product can only be purchased electronically by customers who have a web subscription agreement. Additional sources of applied load that are not included in the rated load may signi? The loads experienced when landing on and hanging from the spider while running and pulling riser may be simulated. This ensures that you are always up-to-date and saves you both time and money.

The rated loads are as follows: No elongated slag inclusion shall be allowed which has a length equal to or greater than shown in Table 3. Since this stress is necessary to equilibrate the axial force, it is a general primary membrane stress.
